To all whom t may concern.'

Beit known that l, HENRY lV. A. Palmen, a citizen ot' the United titates, and a resident ot' Chicago, county ot' Cook, and State et Illinois, have invented certain new and use- `iul .linproveinen ts in Metal Baskets, et' which the following is a specilieation- T he` invention relates to metal baskets ot the type tornied ot a sheet inet-al strip that is slitted and expanded to 'forni diamond niesh and seeks to provide an improved con* struction which is of uniform strength throughout.

The invention consists in the 'features ot improvement hereinafter set i'orth, illustrated in the accompanying drawing and n'iore particularly pointed out in the appended claims.

"In the drawings:

` Fig. l is a vertical section ot proved basket;

Fig. 2 is an enlarged detail view illustrating the inanner of uniting the opposite edges ot the expanded inetal basket body; and

Fig. 3 is a section on the line 3 3 ot Fig. 2. i J c The basket body a is iorined ot a single section or strip of sheet metal which has been slitted and expanded to 'orm unitorin dianiond mesh having two series of oppositely :inclined strands l() united at their intersections by integral bonds l1. The corners ot' the opposite zig-Zag or sinuous edges ot the strip are united so that the original slits of the sheet extend vertically ot the basket body and the direction in which it has been expanded extends circumferentially thereof. It is also noted that when the strip is Abent to cylindrical Ytorni the bonds 1l are arranged in planes slightly inclined to the radial. The basket body is usually further expanded in circumferential direction to lforni a flaring upper end and also to give it a gradual taper `from top to bottoni. Such a structure, for the inost part, is extremely the `iin- 1 rigid in vertical direction or at right angles rows oit bonds ll are quite short and hence the body ot the strip is quite rigid in vertical direction. the strand sections 10L are ot double length and dil'liculty has been encountered in providing `a siinple, strong, sightl'y joint between these edge portions.

ln accordance with the present invention the corners or central portions ot the double length strands 10a atthe opposite sinuous or Zig-zag edges of the expanded nietal strip are overlapped, as niost clearly indicated in Figs. 2 and 3, and the overlapped contacting portions ot these strands are ri gidly welded together, preferably by means et suitable electric welding devices. The contacting corners or welded portions l2 et the meshes are in line with alternate transverse rows ot the bonds l1 and torni in effect bonds at the central portions of the strands 10 of double length at the opposite sinuous edges of the expanded metal strip. Hence, the strands and connections or bonds at the joined edges ot the strip are substantially the saine as the other strands and bonds and Ithe entire basket body is substantially uniform in structure, strength and appearance throughout. It is also noted that the welded portions 12 of the strands 10a, like the bonds ll, are arranged in planes slightly inclined to the radial. Furthermore, this inanner ot 'forming the oint between the opposite edge portions ot the expanded metal strip can be readily and economically etlfected, and it is `particularly well adapted to prevent distortion of the body7 when it is further expanded and shaped, as shown, to provide a gradualvtaper and a. flaring upper end..

After the basket body is orined as described, the portions of the strands at its upper and lower edges are bent around apair of nieta-l stijl'leningy rings 13 and a finishing strip le is bent or claniped upon the portions of the strands that encircle the ring 13 at the upper edge of the basket. The basket is provided with an iinperforate sheet Inetal bottoni Z) having an upturned flanged edge 15 which is bent or clamped about the lower stiffening ring 13 and the lower outturned end of the expanded inetal body.` Preferably also, an impertorate sheet inetal collar c is snugly fitted within thev lower portion ot the basket body and is secured in position by gripping its outturned lower edoe 1G But at its opposite sinuous edges between the edges of the basket body and bottom as shown, or by welding it to the bonds ll at the lower edge portion ot' the basket body. The collar c is formed et a straight strip of inipertorate sheet metal having its ends securely united by' a suitable joint or seam 1T and having an outturned or flaring upper edge 1S that snugly engages the basket body.

Obviously, changes may be made in the details set forth Without departure from the essentials of the invention as delined in the claims.

I claim as ny invention:

l. A basket body comprising a sheet of expanded metal having diamondshaped meshes with the outer side coiners of the meshes at one edge et the sheet in line With the corresponding` corners of the meshes at the other edge ol the sheet, the sheet being shaped into basket form and the meeting corners ot' the meshes Welded together.

2. A metal basket comprising a body formed of a single sheet of expanded metal having diamond-shaped meshes with the outer side corners ot' the meshes at one edge ol the sheet in line with the corresponding corners at the other edge ol'I the sheet, the sheet being shaped into basket form and the meeting corners ot the meshes Welded together, the direction ot expansion of the sheet extending circumterentially ot the basket, and a stitening ring and a stilening bottom united to the upper and lower edges respectively oit said body.

A basket comprising a sheet oil expanded metal having diamond-shaped meshes with the outer side Corners of the meshes at one edge of the sheet in line with the corresponding corners of the meshes at the other edge of the sheet, the sheet being shaped into basket form, ot substantially uniform structure throughout, with the direction ot expansion extending circumferentially thereof and With the meeting corners of the meshes welded together and arranged in planes slightly inclined to the radial.

d. A metal basket body comprising a single sheet of expanded metal having diamond-shaped meshes formed of two series of thin, flat, oppositely inclined strands united at their intersections by rows ot' integral bonds and With the corresponding outer side corners el the meshes at the op posite edges of the sheet in line with one another and with alternate rows oi bonds, the sheet being shaped into basket term and the portions oi' the strands forming the said outer side corners of the meshes over-lapped and Welded together to provide a basket body of substantially uniform structure throughout with the direction of expansion extending circumterentially thereotl and the bonds and Welded portions slightly inclined to the radial, substantially as described.
